Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.
As shown in fig. 1, according to the embodiment of the utility model provides a from sealed high-frequency high-speed two-way valve of buffering, including valve body 1, 1 middle part of valve body is equipped with valve rod 2, 2 one ends of valve rod stretch out the outside of valve body 1, 2 other end fixedly connected with case 3 of valve rod, 1 top of valve body is close to valve rod 2 and is equipped with first guiding mechanism 6, 1 cavity of resorption of valve body is close to case 3 and is equipped with second guiding mechanism 7, be equipped with a plurality of buffering holes 4 on the case 3.
In a specific embodiment of the present invention, the left and right sides of the valve body 1 are provided with a fluid inlet 8 and a fluid outlet 9.
In a specific embodiment of the present invention, a valve is fixedly installed above the valve core 3.
In the utility model discloses a specific embodiment, fixed mounting has disk seat 5 in the valve body 1, disk seat 5 middle part is equipped with the through-hole, slidable mounting has the valve in the through-hole.
In a specific embodiment of the present invention, the fluid of the fluid inlet 8 flows into the fluid outlet 9 through the through hole of the valve seat 5.
For the convenience of understanding the above technical solutions of the present invention, the above technical solutions of the present invention will be described in detail through specific use modes.
A from sealed high-speed two-way valve of high frequency of buffering is applied to fluid valve technical field, main valve body 1, valve rod 2 and case 3 are constituteed.
When the valve core 2 moves in the valve body 1, the valve core moves in the cavity similarly to the movement of a piston, the first guide structure 6 controls the running track of the valve rod 2, so that the valve rod 2 always keeps linear motion, the second guide structure 6 controls the running track of the valve core 3, so that the valve core 3 always keeps linear motion, and the valve rod 2 and the valve core 3 can be in a stable motion state. Therefore, a high frequency and high speed linear motion can be realized.
After fluid enters the inner cavity of the valve body, the fluid enters the lower cavity of the valve core 2 through the buffer hole 4, and when the valve is in a full-open state at the initial position, the pressure of the fluid medium in the lower cavity of the valve core 2 acts on the surface of the lower cavity parallel to the sealing surface of the valve core 2 to form an auxiliary closing force to help the valve to be quickly closed.
When the initial valve position is at half full, the lower chamber of the valve element 2 is still filled with fluid medium. If the fluid is incompressible, the expulsion of the fluid will help slow the valve opening. In the case of compressible fluids, the fluid will create a reaction force during compression, which will also slow the opening speed. The form of fast switch and slow switch can be suitable for the working condition of special application.
To sum up, with the aid of the above technical scheme of the utility model, realized high frequency and high-speed linear motion, guaranteed life-span and good leakproofness of using simultaneously, the buffer hole of case has realized that the fast switch is opened slowly.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
